Error: Failed to get SMART data

[Jay2k1]

Hi,

I am trying to deploy the plugin to a host and test it there (run the python plugin file manually). I get:

<<<oposs_smart_error:sep(124)>>>
/dev/sdc|ERROR|Failed to get SMART data

The host has four disks (sda through sdd), two are SATA SSDs and two are SATA HDDs. All disks are connected to the (Supermicro) mainboard (no RAID controller, no HBA).

I looked through the code and ran the commands manually. What I've noticed is that it allows smartctl exit codes of 0, 1, 2 and 4. However, running it against sdc exits with 64. This is the output:

# smartctl --info --log=error /dev/sdc; echo $?

Error 1 occurred at disk power-on lifetime: 34583 hours (1440 days + 23 hours)
  When the command that caused the error occurred, the device was active or idle.

  After command completion occurred, registers were:

64

So I thought I'd add 64 to the "allowed exit codes", but then the check just doesn't output anything for my disks.

Did I miss something?
